您好，现在开始在 Android 中构建小型应用程序。我尝试通过调用 Call Intent 来启动按钮单击呼叫。我已经在 Manifest 文件中设置了必要的权限。

但我仍然收到错误消息

com.android.phone 停止工作

在此处输入图像描述

<Linear Layout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

<Button 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/btnShow"
    android:text="@string/btnShow"
    android:fontFamily="sans-serif" />

      </LinearLayout>

MainActivity.java

package com.example.androidproject2;

import android.app.Activity;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity
{

    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btnShowDialer=(Button) findViewById(R.id.btnShow);
        btnShowDialer.setOnClickListener(new View.OnClickListener()
        {

            @Override
            public void onClick(View arg0) {
            try
            { Intent callIntent=new Intent(android.content.Intent.ACTION_CALL,Uri.parse("tel:1121121212"));
                startActivity(callIntent);

            }
            catch(Exception e)
            {
                Log.e("Trail","Call Falied", e);
            }

            }
        });
    }

}

试试看

Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:1121121212"));
                startActivity(callIntent);

试试看

button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:0377778888"));
                startActivity(callIntent);

            }

        });

并确保在清单中添加以下权限

<uses-permission android:name="android.permission.CALL_PHONE" />

Logcat 消息和您的布局不是来自同一运行。

Logcat 错误清楚地表明：

在 id 为“btnShow”的视图类 android.widget.Button 上的 onClick 处理程序的活动类 com.example.androidproject2.MainActivity 中找不到方法 showDialer(View)

这意味着您的真实布局不是您在此处发布的内容。我很确定它包含这样的内容：

<Button 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/btnShow"
    android:text="@string/btnShow"
    android:fontFamily="sans-serif"
    android:onClick="showDialer" />

注意android:onClick="showDialer"，这就是 Logcat 告诉你的。

从布局中删除该行，或者创建方法 showDialer 并删除 setOnClickListener()。
